Right in the city centre, it sprawls over several pedestrian streets and some parts are covered. Athonos Square, a spot for small traditional shops that offer spices and food products, handmade patio furniture and wicker crafts. Some jewellery, clothing and craft designer shops have sprung up in the last few years. Modiano Market was built in the 1920s and resembles some Parisian markets. Here you'll find traditional food items and a good selection on modern and old-fashioned tavernas.
